Problem 1

Find the length of the square, where the area of the square is 391876 cm².

Okay, lets begin

The area of a square = a²

So, the area of a square = 391876 cm²

So, the length = √391876 = 626.

The length of each side = 626 cm

Explanation

The length of a square is 626 cm.

Because the area is 391876 cm², the length is √391876 = 626.

Problem 2

Sarah is planning to carpet her square room of length 626 feet. The cost to carpet a foot is 3 dollars. Then how much will it cost to carpet the full room?

Okay, lets begin

The length of the room = 626 feet

The cost to carpet 1 square foot of the room = 3 dollars.

To find the total cost to carpet, we find the area of the room,

Area of the room = area of the square = a²

Here a = 626

Therefore, the area of the room = 626² = 626 × 626 = 391876.

The cost to carpet the room = 391876 × 3 = 1175628.

The total cost = 1175628 dollars

Explanation

To find the cost to carpet the room, we multiply the area of the room by the cost to carpet per foot. So, the total cost is 1175628 dollars.
